2 questions; operating temperature and oil leaks

[Gravy]

That brings up what I call a "Well, duh!" moment - teflon tape should have been the first sealant I mentioned...

Oh well, you know what they say about CRS...geeze, I can't remember that either...

By the way I had to take the cover off the side of the engine to get at the sender, so I decided to blow out the air-cooling fins.

WOW! There was a LOT more crud in there than I was expecting. It's no wonder I was running a little hot. Took about 10 minutes with the air hose to knock all the stuff loose. Lots and lots of those dreaded Fluffy Seeds. 'Glad I caught that one...

And I've found that when I take the top cover off and hold a piece of white paper underneath there are still places that air hasn't dislodged the last few blockages.

Fortunately, our Spring has been wet enough that I don't anticipate much chaff when I do the first cutting this week. /forums/images/graemlins/grin.gif

Cleaning that sucker every hour has to be my least favorite PT1845 operators task. My mowing last week of last years weeds was done in a cloud of chaff that easily defeated my best attempts so far to filter it out. I've got no opening bigger than insect screening and the fine stuff still gets through and clogs the fine passages in the cooler. I mowed about 4 hours and had to disassemble the engine and clean that sucker 4 times. Then it started raining and I got to mow in the rain for several hours with no overheating at all. Grin. Gotta remember that little trick since by now it's gotten pretty obvious PT isn't going to offer to filter that oil cooler air for us. /forums/images/graemlins/tongue.gif

Mowing is my new rainy-day job,

John:
Back when you and I were first starting to try to eliminate the right side stripe, before we installed high lift blades, etc., I found also that the machine with the stock 3/8 thick blades did a more even cut in the rain. The only part of the system not improved by precipitation was the operator. /forums/images/graemlins/tongue.gif

So maybe the water adds mass/momentum to the light wispy stuff making it stand there and take the hit of the blade instead of being such a pushover. We like it.

But Charlie, it's only water. Mowing with a PT is at least as much fun as golf and everyone knows it never rains on a golf course. /forums/images/graemlins/smile.gif

With a nice hot beverage in the water bottle and no need to come out from under the canopy to clear the chaff, how ya going to get wet anyway? /forums/images/graemlins/tongue.gif

Maybe I'm all wet... /forums/images/graemlins/tongue.gif

Have either of you guys thought about mounting an air compressor in your engine compartment for in-the-field use? Is there even room? Just wondering.

Not to hijack the thread, but on the subject here of engine chaff, has anyone used one of the Engineaire Filter systems, or have a good way of dealing with the air filter clogging?

Engineaire

Seems like they can adapt their systems to most any engine requirement. On my Robin-powered unit, I find that I am cleaning my sponge filter element with every use. I've mowed 4 times so far this season, and between the chaff, tree pollen, etc. the filter is very heavily clogged at the end of a single mowing session. To clean it well, it takes me at least a pint or more of Kero, and then a final saturation w/ a kero/oil mix.

Our Kohler has almost 200 hours on it. I have cleaned the air filter only according to the Kohler manual. It really only needed cleaning one time. The other times, it was very clean. It is just a foam element over a paper element. Makes me wonder if my vision of a dirty environment is different from every body else's as I thought I was in some extremely dirty areas at times. /forums/images/graemlins/crazy.gif

I believe that the thread on the sender is pipe thread. If it's leaking around the threads, reseal and re tighten. If it still leaks, through it away and get a new one, should be less than $10 bucks.
